 VIOLET FOKCING. To obtain Neapoli- 

 tan Violets in winter, select a warm, shel- 

 tered corner; cast out trenches a foot 

 deep and five feet wide into the alleys, 

 and make a turf wall all round to the 

 desired height, for holding about fifteen 

 or eighteen inches of leaves, rubbish- 

 heap refuse, or any fermenting materials 

 likely to afford a little bottom-heat, upon 

 which place about eight or nine inches 

 of rich, open soil. The width regulate 

 by any lights to be spared for a time, or 

 thatched hurdles, or other protectors. 

 The plants take up from the store plan- 

 tation carefully, with balls of earth to 

 their roots, and plant from ten to twelve 

 inches apart each way, first clearing them 

 of any side-shoots or suckers ; afterwards 

 keep clear of dead leaves, &c., well sur- 

 face-stir, and never allow to get dry. No 

 lights or protection are to be placed over 

 them, until frosty nights set in, or very 

 heavy rains; then, at all times, tilt on 

 both sides, with abundance of air, if the 

 weather is not too severe. By such 

 treatment the foliage is always large, 

 thick, and of a beautiful dark green, the 

 flowers abundant and large. No side- 

 runners are to be allowed to run until 

 April, at which time they are to be en- 

 couraged to grow ; and open, sandy, rich 

 soil sifted amongst them, and kept well 

 watered, to encourage them to root freely. 

 A partially-shaded piece of good ground 

 is then to be chosen in the month of 

 May, and the Violets then forked up, old 

 and young altogether, and the best of 

 the young plants selected and planted 

 out a foot apart each way singly. They 

 are to be kept well surface-stirred all the 

 summer, and by October they will be fine 

 plants to take up as above described. 



Russian Violets Single White, Double 

 White, Double Slue, and other hardy 

 varieties grow in a similar way, with 

 regard to planting out the young runners 

 and summer treatment, and they are also 

 to be carefully taken up in October ; some 

 placed in turf-pits, with gentle bottom- 



heat, and some without bottom-heat, and 

 a quantity planted on sloping banks. By 

 this simple contrivance abundance of 

 luxuriant flowers are kept in succession 

 from September till May. Every variety 

 is kept clear from side-shoots or runners 

 all the summer. All the varieties are 

 particularly fond of charred articles mixed 

 with the soil.

 to Catchfly.) 



Seeds in open border, in April ; or in a shel- 

 tered, dry place, in September; perennials, by 

 seeds and divisions; dry garden-soil. Lychnis 

 ulpi'na and Helvetica have been added to thi- 

 genus.

VI'SCUM. Mistletoe. (From viscus, 

 bird-lime; the berries contain a viscid 

 matter like bird-lime. Nat. ord., LorantJis

The Mistletoe thrives best on the thorn and the 

 apple. The seed, in early spring, should be 

 squeezed from the berries into crannies of the 

 bark underneath a branch, or slits h* made on 

 purpose in the bark.
